Benefits of technology

This patent describes a dental device that can show a root canal in a tooth on a two-dimensional image taken with visible light. This allows dental surgeons to better understand and operate on the tooth in a more accurate way.

Problems solved by technology

For example, it is difficult to accurately grasp the position of the root canal orifice inside the tooth while checking an image of the surface of the tooth captured by the optical camera or the microscope.
There is a risk that the root canal is excessively cut even into the healthy area other than the root canal orifice, which may result in the breakage of the tooth referred to as “root canal fracture”.
